EPBCIPICATION forming part oi- Letters Patent No. 349.352, dated September 21, 1886.

Application filed November 5, 1883. Serial No. 110,878. (No model.) Patented in England May 10, 1883, No. 2,383; in Germany October 9, 181 3, No. 27.686, and in France November 9, 1883, No. 158,448.

hereinafter mentioned for insurin a 3erfeet selvage, and B shows the new position of I 5 the parts for effecting the same object; Fig. 2, a transverse sectional elevation of a Cotton knitting-machine such as that we propose to improvc,the position only of those cams which are to be replaced by other cams being in- 20 dicated by dotted circles; Fig. 2, a partial plan view of the left-hand end of the machine; Fig. 2,a partial end view of the machine; Fig. 2, an enlarged transverse sectional elevation of the upper portion of the machine; Fig. 2, 2 5 a front elevation of the complete machine embodying our improvements; Fig. 2", a partial transverse sectional elevation showing particularly the sliogging-cam, tappet-chain, and the immediate connecting mechanism; Fig. 3, a partial sectional elevation showing particularly the needle-bar mechanism; Fig. 4,asimilar view showing particularly the levers and cams for operating the catch-bar; Fig. 5, a similar view of the modified mechanism for 5 giving motion to the snapping apparatus; Fig. 6, a partial longitudinal sectional elevation showing particularly the modified mechanism for giving two traversing motions to the threadcarriers for one'rotation of the camshaft. Figs. 4c 6* and d show, respectively,detached views of the miter-wheel, its clutch, and the camshaft, and the cam and shogging shafts and friction-clip, with a portion of the supporting frame-work; Fig. 6, a detached View of the cam 5 employed for imparting the motions to the thread-carriers. Figs. 7 and 8 show, respectively, in front and sectional elevation, detached views of the shoggingcam and immediate connecting mechanism. Figs. 9 to 14, inclusive, 5c are detached views of the cams hereinafter par ticularly referred to. Figs. to 21, inclusive, are enlarged diagrams illustrating the various motions of the knitting instruments.

Figs. 22 and 22, 23, and 23 are diagrams of cams to be hereinafter referred to.

The object of this invention is to increase the production of knitted work in straightknitting machines furnished with the wellknown Cotton traversing thread-carriers, as shown and described in the United States Patcut granted to \Villiam Cotton, and dated November 20th, 1886, No. 59,892.

This object we successfully attained by an arrangement of mechanism which formed the subjectof United States Letters Patent granted 6 to us and hearing date January 16, 1883, No. 270,682. In the specification of that patent we described the use 'of a rowof points which served to receive the threads from the threadcarriers and transfer them in a divided state to the stems of the needles. This produced great economy in point of time, as it enabled the consecutive operations to be brought more closely together than heretofore, so much so, indeed, as to permit of the duplication of the 7 5 various operations during one rotation of the camshaft without interfering with the fashioning of the work. We now propose to effeet the like result without the use of this row of points, and thereby to simplify the con- Sc struction of the machine. For this purpose we so alter the ordinary Cotton knitting-machine as to modify the motions of the jacksinkers, the dividing-sinkers, and also of the needles. In the old machine thejack and di- 8 5 viding sinkers were given two advance motions for each course, the first motion of which was to effect the sinking or drawing off of the thread to the extent desired for the loops of the particular fabric being produced, and the second being to secure, as is well known, two things-viz.,the holding down of the work and the prevention of the thread (while the needles were just emerging from between the sinkers) from slipping to the inner side of the 5 selvage-needles, and thereby forming an imperfect selvage. In the present construction we give to the sinkers but one advance motion for the course, instead of two, as heretofore, the said second movement being dispensed 10
